[comp.sys.sun] Root password and single user boot

jbauman@decwrl.dec.com (06/05/91)

Is there a way to prevent someone from stepping up to
a workstation, giving the Sun 2 fingered salute (L1-A), booting single
user, modifying the password file (i.e. removing a root password),
then coming back on the net to pursue "other activities"? Surely there
must be a mechanism to ask for the root password even after booting single
user.....

Thanks for the help...

From the ttytab(5) man page:

If  the  console  is not marked "secure," the system
prompts for the root password before coming  up  in  single-
user  mode.

So, in your ttytab file remove the word secure from the console line.
